Each mL contains the equivalent
of 50 mg of elemental iron
(as an iron dextran complex), approximately 0.9% sodium
chloride, in water for
injection. Sodium hydroxide
and/or hydrochloric acid
may have been used to adjust pH. The pH
of the solution is
between 5.2 and 6.5.

The iron dextran
complex has an average
apparent molecular
weight of 165,000 g/mole
with a range of approximately
±/- 10%.
